IMPROVEMENT IN RECLlNlNG-CHAIRS.

Specification forming part of Letters Patent No. 118,719, datedSeptember 5, 1871.

To all whom it 'may concern.:

Be it known that I, WILLIAM HEATH, of Bath, in the county of Sagadahocand State of Maine, have invented a new and useful Improvement inReclining-Chairs, and do hereby declare the same to be fully describedin the following specification and represented in the accompanyingdrawing, in which Figure 1 is a top view, Fig'. 2, a side elevation,Fig. 3, a rear elevation, Fig. 4, a vertical and longitudinal section ofa chair provided with or constructed in accordance with my invention.

In this chair the seat A is pivoted at or near the middle of each end ofit to the leg-frame or rests and turns upon a rod or shaft, B, arrangedat or near the middle of such seat and extended across and supported bythe leg-frame C. At its rear the seat has inclined legs D D, which, whenthe back E is upright or elevated to its highest position, rests on thelower bar ay of such back.

I The back is pivoted to the leg-frame at b b, parts of the back beingextended below the pivots and having the seat arranged between the saidparts. There is hinged to the lower bar a of the back a bar, F, providedwith an inclined plane or cam, G, arranged with the bar, in manner asshown. This cam G rests on the front cross-bar or girt c of theleg-frame and between guides or posts d el extended up therefrom, asshown. At the front end of the bar F there is a frictionroller, e, thatbears against an arm, H, which, at its upper end, is hinged to the seat.The lower part of the arm H bears against the legrest I, which, at itsupper corners, is pivoted to the seat. From the pivots .r of theleg-frame there project upward two arms, Il I', to whose upper parts andto the back arm rests or rods K K are pivoted, all being as represented.A pawl, L, hinged to the seat and arranged as represented by taking intoa notch, g, made in the bar F, when the back is at its highest position,serves to estop any forward movement ofthe said bar F, and,consequently, any falling of the back and raising of the leg-rest.

From the pawl a line or cord, h, is led upward to a guide, 1',projecting from the seat, thence through a guide, k, arranged in oneside bar of the le g-franie. By laying hold of such cord and pulling 011it the pawl may be raised out of the notch. While the back may be in theact of being declined the bar F will be moved forward and will carry theinclined plane with it. The conjoint operation of the two will cause thelegrest to be forced upward.

If desirable there may be two of the bars F, each provided with a cam,as set forth, they, nnder such circumstances, being arranged near thesides of the leg-frame.

While the back may be in the act of being depressed the seat will tipbackward or fall at its rear and rise at its front, thus securing averyeasy position of it for the person who may be in the use of the chair atsuch time. As the back continues to descend to or near a horizontalposition the seat will be raised to or about a horizontal position andthe leg-rest will also be elevated.

From the above it will be seen that the seat has no sliding motionforward while the back is being manipulated or worked.

By the action of the lower bar of the back against the seat while theback is being depressed such seat will be raised, it falling while thesaid bar is acting against the inclined legs of the seat.

In the said chair I claim as my invention the following, viz:

1. The back E and the seat A, arranged with and pivoted to the leg-frameC, as set forth, and provided with the cross-bar ay and the inclinedlegs D D, or their equivalents, to enable them to operate substantiallyas specilied.

2. In combination with the back E, the seat A and the leg-frame (l, thebar F, the cani G, the arm H, and the leg-rest I all'being arranged andapplied together, substantially as specitied.

WILLIAM HEATH.
